Roger, client dropped off this leather ottoman. It is very faded but has some areas where the original color appears to have come back to surface from a spill, or had something on it early on and never faded in these areas. she wants it restored along with sofa and another chair. We will be going to her house to take pictures and inspect the other furniture. It appears to be a semi aniline. Either aniline 76 or Antique to cover? there is also some catch scratch on surface of this ottoman that should be repaired., so I will need a dye that can help cover those.

How should I proceed with ottoman to see if I can make it even prior to dye.

top view of ottoman, shows very dark stains/ discoloration or actual color.

Side view of ottoman, showing how faded it is, color between cushion and frame looks perfect and is very close to dark areas on top of ottoman.

>>> Roger, should we just clean, rinse, hydrate, and fatliquore? Or should I prep clean with ???

Follow the following sequence:

A - Restorative Cleaning:
When re-dyeing is in mind use this system.
Use Degreaser-2.2 > Acidifier-2.0 for above surface and Hydrator-3.3 for below surface.

B – Hydrating:
One function of Hydrator-3.3 is activating dormant dyestuff to resurface and this is performed under evaporation control with plastic covering and dwelling for up to 72hrs.

C – Fatliquoring:
Hydrator-3.3 > Fatliquor-5.0 > Fatliquor-5.0 system rejuvenate the leather suppleness with softness and strength.

D – Repairs:
Bond-3D system

E – Re-dyeing:
When colors are original dark, Aniline-76 for an even appearance is a better choice to maintain original value of the leather. Translucent finishing lower its value, opaque finishing drastically downgrade and may not live up or comparable with surrounding furnishing.

F – Topcoat:
A choice of gloss or satin, In most cases the gloss is used first for strength and satin is to adjust the luster level to taste.

G – Protection:
Protector-B+ reduces the wear and tear and if used on a routine basis will prolong the wear of the finishes.

Roger, We need help deciding which dye to use. There are some cat scratch areas on surface of ottoman. I was thinking to use Antique-27 so i could do a little repair to scratches and bring back the color too.

After cleaning, hydration fatliquor. Thought it looked way too dark, but think it looks much improved.

4121
This is where we pushed top surface down to show against untouched area that has been protected from environment.

4122
color di not come back to sides like it did to the top where it was so dry and worn.

>>> Roger, We need help deciding which dye to use.

Dyestuff from transparent to translucent may be used in this sequence of the same color range.

1st – Aniline-21 may be used but be aware that different absorbency rate may produce different color intensity. It only stains the leather protein fiber and may not stain the existing topcoat making scratches and worn areas more obvious compare with topcoat intact areas. Unless the topcoat is first stripped with Stripper-2.3 and a mist test with Hydrator-3.3 to ensure even surface tension with an even appearance. Color intensity is reduced with distilled water or to increase adhesion as well, Adhesor-73 or Aniline-76 Clear is also used.

2nd – Aniline-76 coats over existing topcoats and any surface repairs with Adhesor-73 as well. This will provides a more even appearance. Color intensity is reduced or adjusted with Aniline-76 Clear.

3rd – Antique-27 is a translucent coating dyestuff and only used where light to medium color is the priority. Obscure the blemishes but also kills the beauty of depth and does downgrading the quality of aniline leathers to a dye-pigment hybrid.


>>> There are some cat scratch areas on surface of ottoman.

Surface cat scratches detectable by hand is corrected with Adhesor-73 and fine 1500/2000grit during in-between sanding.


>>> I was thinking to use Antique-27 so i could do a little repair to scratches and bring back the color too.

Quite common to see natural healing scratches normally darker on aniline leathers. Check with your customer preference before doing so. I would go with Aniline-76 and it is still not too late to slightly dull it up with Antique-27.

Use Eraser-4, work on half and show some pictures!

The lighter shade is probably the existing topcoat – use Stripper-2.3 and work with nylon stripping detailing brushes. Test with Hydrator-3.3 to inspect darkening penetration. When all the existing topcoat is removed, hydrate to dwell up to 72hrs to reactivate existing dyestuff to re-surface. The objective is to narrow the color appearance prior to redyeing it. Otherwise the color difference may still show through with transparent Aniline-76 dyestuff.

Recommended Re-dyeing system:

4139

Leather Doctor® Kit-A7.cl, aniline leather dye refinishing kit is designed for dyestuff and topcoat refinishing from the simple sunlight fading to the severely sweat damages from body oil and grease. Most severely penetrated, prolonged and neglected stains show a darkening effect with a sticky feel have its topcoat and dyestuff probably deteriorated by the sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from breaking of bonds with the tanning agent. When sign of color is transfer to a white towel, it indicates that the dyestuff has also break bonds with the protein fiber. When leather is stiff or shows signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH mainly caused from sweat to alkalinity affects the pH imbalance. To revert from denaturing into rawhide prior to topcoat refinishing, contaminated alkaline soiling is removed with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies greasy contamination besides controlling dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse and pH balanced with Acidifier-2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of a healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Custom redyeing commences prior to topcoat refinishing. Protector-B+ imparts a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline leathers dyestuff and topcoat refinishing system.

Please email [email protected] for custom matching services or choice of color: Antique-Brown, Black, Yellow, Orange, Red, Red-Brown, Rubine, Blue or Dark-Brown. And choice of topcoat luster: Gloss or Satin.

A few concerns after cleaned and hydrated and fatliquored. It has a distinct dark to faded areas, I think we can bring back more color and make lines less defined to get a better final finish. How would you proceed from here?

Back of chair, hazy area is non absorbant, darker area is highly absorbant. We experiemented with stripper and 3m pad and it made very little difference. do you have an idea on how to break through the finish so it will be more uniform?

>>> Prior to cleaning

This leather looks Aniline Wax Pull-up- we need positive identification.


>>> Started cleaning cushion- note where Degrease 2.2 is applied.

Any particular reasons?


>>> Left arm
The leather is faded but when some liquid is spilled it brings forth the dye from beneath.


>>> Top of back
Again looks like an Aniline Wax Pull-up – but need positive confirmation.

Noted.

For all the above solution to the problem is having the topcoat shaved off with Razor-60 in conjunction with Hydrator-3.3 acting as lubricant so that it smoother to shave without hurting the grain. Inspection is done in conjunction with dry shaving. Thereafter the blotchiness is rectified or even out with Hydrator-3.3 for a much even appearance prior to color refinishing. And since this could be a wax pull-up, preparing the base with Adhesor-73 thoroughly with scouring pad will ensure no peeling issues.
